Patent number: 4490364Abstract: Analogs of CCK(1-8) having dissociated activity with respect to stimulating the contraction of the gall bladder and arresting the secretion of gastric acid. Various analogs also exhibit improved anticonvulsive potency. The peptides are characterized by the following formula:X--R.sub.0 --R.sub.1 --Tyr(Y)--R.sub.3 --R.sub.4 --Trp--R.sub.6 --R.sub.7 --R.sub.8 --NHQwherein X is H, Suc, Ac, Oxa, Mal, Glt, Prp, Prl or Acr; R.sub.0 is Gln, pGlu, Cys, Tyr, Tyr(OCH.sub.3), des--NH.sub.2 --Tyr or desR.sub.0 ; R.sub.1 is Asp, Tyr(OH or SE), Ser(OH or SE), Hyp(OH or SE), Thr(OH or SE), Cys, Tyr(OCH.sub.3) or desR.sub.1 ; Y is OH or SE; R.sub.3 is Met, Nva or Nle; R.sub.4 is Gly, D--Cys or D--Ala; R.sub.6 is Met, Nva or Nle; R.sub.7 is Asp, Ser(SE), Thr(SE) or Hyp(SE); R.sub.8 is Phe or Tyr(OCH.sub.3); and Q is lower alkyl, fluoro lower alkyl or hydrogen; provided that when R.sub.3 and R.sub.6 are Met and R.sub.7 is Asp then R.sub.4 is D--Ala. A pharmaceutically acceptable salt thereof may also be employed.Type: GrantFiled: August 12, 1983Date of Patent: December 25, 1984Assignee: The Salk Institute for Biological StudiesInventors: Jean E.
